Police were called to the Playboy mansion today due to a 911 call. It was initially thought that it could have been a 'swatting' prank.

The Los Angeles Times reports that police went to Hugh Hefner’s mansion after receiving the call around 7 a.m. LAPD spokesman Richard French said that area residents “have stated everything was fine.” When they arrived, they didn’t see any signs of an assault or any incident.

While French did tell the media, “It could be one of those swatting calls,” TMZ is now reporting that police don’t think that Hefner was another ‘swatting’ prank victim. The site’s sources say that police have figured out who the caller is and they did not send a full SWAT team to the mansion. Only two squads responded to the call.

TMZ’s sources add that the caller may have genuinely believed that an assault was taking place.

Police weren’t the only ones who initially thought that it was a prank. Hefner wrote on Twitter, “A crank call brought police to the Playboy Mansion early this morning. Other celebs have been victims of recent hoaxes.”

Several celebrities in Los Angeles have been victims of ‘swatting’ pranks, including Ashton Kutcher, Justin Bieber and Chris Brown. A 12-year-old boy has been charged in connection with the prank on Kutcher.
